SAFET Y-STIRRUP.

To all whom it may concern:

Be it known that 1, DAVID SAMSON, a citizen of the United States,residing at Chambers, in the county of Holt and State of Nebraska, haveinvented certain new and useful Improvements in Safety Stirrups, ofwhich the following is a specification.

This invention relates to improvements in safety stirrups for saddles,and has for its object to provide a stirrup of this class consist-ing offew parts so that the same may be economically constructed, and whichwill be reliable in operation and durable in wear.

The invention has reference to a structure providing a removable treadplate, said tread-plate being operated by a curved releasing-barpivotally mounted at the ends of the yoke or loop of the stirrup, eachof the upright arms of the releasing-bar, when in its normal position,being housed in a recess formed between the outer and the inner sides ofeach arm of the yoke, so that the upright arms of the releasing-bar willnot become readily detached from their supports, said supports beingupon certain lugs or ledges and will not engage the boot or shoe of therider, the free ends of the yoke being employed for a pivotal mountingthereon of the tread-plate.

With these objects in view, the invention presents a novel construction,combination and arrangement of parts as herein described and claimed,and as illustrated in the drawing, wherein,

Figure 1 is a vertical rear view of a stirrup embodying my invention,one of the lower ends of the yoke being partly in section to disclosethe mounting of the stirrup iron or tread-plate. Fig. 2 is alongitudinal sectional view of the yoke. Fig. 3 is an end view of thetread-plate, and shows the angular releasing member mounted thereon.Fig. 4 is a vertical sectional view on line a a of Fig. 1.

Referring now to the drawing for a more particular description, numeral1 indicates the yoke of a stirrup, the arms 2 thereof being formedupwardly convergent near their junction and provided with recesses 3opening outwardly upon their terminals; and preferably the arms of theyoke have outwardly curved portions 4 between their terminals andconvergent portions mentioned.

Upon the inner side of curved portions 1 of the yoke arms are formedreduced portions or recesses 5, the same extending longi- Specificationof Letters Patent.

tudinally thereof and opening upon recesses 3; and the arms of the yoke,'midway between their upper and lower ends, are provided with recesses 6extending transversely thereof upon their inner sides, and recesses 6open upon the upper terminals of recesses 5 and inwardly of recesses 6are provided projections or ledges 7 which operate as lugs.

At 8 is indicated a tread-plate, its ends having curved bearing portions9, their conveXed surfaces conforming to the concaved surfaces ofrecesses 3.

I provide the tripping member 10, the same being formed as a U-shapedloop bent angularly and forwardly between its ends, as indicated at 11,and thereby providing upright supporting arms 12, transverse engagementarms 13, and an integral terminal 14.

Arm-portions 12 are curved to correspond with the curvature of recesses5, and when assembling the parts, end portions 9 of the tread-plate arefirst seated in recesses 3, and by swinging the tripping memberforwardly or inwardly of the yoke arms 12 will engage within recesses 5,a part of arms 13 engaging lugs or ledges 7, and at this time the entire weight of the releasing member will be supported upon the lugs; andsince armportions 12 are disposed within longitudinal recesses 5- theyare not obtrusive and will not be engaged by the foot of the rider whenthe foot is inserted in the stirrup, and the tripping member will notbecome dislodged from its support upon the lugs; and it will beunderstood that in practice the weight of the foot of the rider, whileseated upon the tread-plate, is supported by the contacting parts ofarms 12 within recesses 5 and arms 13 upon lugs 7 In practice, terminal1% of the loop may be engaged by the foot of the rider to disengage thereleasing member from the yoke. Since the stresses imparted to thetreadplate are supported as described, the device is reliable in use asan ordinary stirrup, and when the parts are assembled, bearing portions9 of the tread-plate will be reliably held within recesses 3.

It will be understood that the function of the safety stirrup is toprovide a device whereby the foot of the rider may be automaticallyreleased from the stirrup in cases of emergency; and the structure, asdescribed, operates for this purpose in a practical manner. Terminal 14of the loop,

When the device is in use, is disposed immediately above the instep ofthe foot of the rider; and in practice an upward pressure upon thisterminal will cause a rearward swinging movement of the releasingmember, whereby arms 13 will be released from ledges 7 and the releasingmember will become detached from the yoke; and on this account the footof the rider will become released from the stirrup. v

At 15 is indicated a flexible member having one of its ends connected inany suitable manner upon the tread-plate, as by staple 16, its oppositeend being secured upon and near the lower end of the yoke, this memberbeing employed for the purpose of preventing loss of the releasingmember when the parts are detached.

Having fully described my invention what I claim and desire to secure byLetters Patent is,-

In devices as described, in combination with the yoke-arms of thestirrup, said arms having recesses formed in their terminals andprovided with longitudinal recesses upon their inner sides, and havinglugs formed intermediate their ends; a treadplate; a loop having itsends secured upon the tread-plate, said loop being bent between its endsto form supporting arms and transverse engaging arms, said tread-plateadapted to have a pivotal mounting in the terminal recesses of the yokearms, the supporting arms being disposed in said longitudinal recesses,said transverse arms engaging said lugs; and a flexible keeper-memberconnecting the treadplate and one of said yoke-arms. V In testimonywhereof I have affixed my signature in presence of two witnesses.
